Nuclear PI-PLCβ1: an appraisal on targets and pathology.

Lipid signalling molecules are essential components of the processes that allow one extracellular signal to be transferred inside the nucleus, where specific lipid second messengers elicit reactions capable of regulating gene transcription, DNA replication or repair and DNA cleavage, eventually resulting in cell growth, differentiation, apoptosis or many other cell functions. Nuclear inositides are independently regulated, suggesting that the nucleus constitutes a functionally distinct compartment of inositol lipids metabolism. Indeed, nuclear inositol lipids themselves can modulate nuclear processes, such as transcription and pre-mRNA splicing, growth, proliferation, cell cycle regulation and differentiation.

Lower rate of cardiovascular complications in patients on bolus insulin analogues: a retrospective population-based cohort study.

Background: Few studies are available evaluating the impact of rapid-acting insulin analogues on long-term diabetes outcomes. Our aim was to compare the use of rapid-acting insulin analogues versus human regular insulin in relation to the occurrence of diabetic complications in a cohort of diabetic patients through the analysis of administrative databases.

Methods: A population-based cohort study was conducted using administrative data from four local health authorities in the Abruzzo Region (900,000 inhabitants).

Efficacy of a nurse-led email reminder program for cardiovascular prevention risk reduction in hypertensive patients: a randomized controlled trial.

Background: Many strategies have been evaluated to improve the prevention and control of cardiovascular (CVD) risk factors. Nursing telephonic and tele-counseling individualized lifestyle educational programs have been found to improve blood pressure control and adherence to lifestyle recommendation. This study tested the efficacy of a nurse-led reminder program through email (NRP-e) to improve CVD risk factors among hypertensive adults.

Five-year retrospective Italian multicenter study of visceral leishmaniasis treatment.

The treatment of visceral leishmaniasis (VL) is poorly standardized in Italy in spite of the existing evidence. All consecutive patients with VL admitted at 15 Italian centers as inpatients or outpatients between January 2004 and December 2008 were retrospectively considered; outcome data at 1 year after treatment were obtained for all but 1 patient. Demographic characteristics, underlying diseases, diagnostic procedures, treatment regimens and outcomes, as well as side effects were recorded.

In vitro reparative dentin: a biochemical and morphological study.

In this study, starting from human dental pulp cells cultured in vitro, we simulated reparative dentinogenesis using a medium supplemented with different odontogenic inductors. The differentiation of dental pulp cells in odontoblast-like cells was evaluated by means of staining, and ultramorphological, biochemical and biomolecular methods. Alizarin red staining showed mineral deposition while transmission electron microscopy revealed a synthesis of extracellular matrix fibers during the differentiation process.

Pregnancy e-health: a multicenter Italian cross-sectional study on Internet use and decision-making among pregnant women.

Background: Our study aimed to estimate the prevalence of pregnancy e-health seekers in a large Italian sample; to explore the factors influencing the choices of the childbearing women regarding their lifestyles after internet consultation; and finally to investigate potential differences between primiparous and multiparous women in internet use to find information about pregnancy.

Methods: A multicentre survey was carried out in seven Italian cities. Data were collected through a validated questionnaire administered in waiting rooms of outpatient departments by medical doctors.

Multicentric cohort study on the long-term efficacy and safety of electronic cigarettes: study design and methodology.

Background: While electronic cigarettes are forbidden in several countries, their sales are exploding in many others. Although e-cigarettes have been proposed as long-term substitutes for traditional smoking or as a tool for smoking cessation, very scarce data are available on their efficacy and safety.We describe the protocol of a 5-year multicentric prospective study aimed to evaluate short- and long-term adherence to e-cigarette smoking and the efficacy of e-cigarettes in reducing and/or quitting traditional cigarette smoking.

Lower incidence of macrovascular complications in patients on insulin glargine versus those on basal human insulins: a population-based cohort study in Italy.

Background And Aim: The aim of this study was to compare the use of insulin glargine and intermediate/long-acting human insulin (HI) in relation to the incidence of complications in diabetic patients.

Methods And Results: A population-based cohort study was conducted using administrative data from four local health authorities in the Abruzzo Region (900,000 inhabitants). Diabetic patients without macrovascular diseases and treated with either intermediate/long-acting HI or glargine were followed for 3-years; the incidence of diabetic (macrovascular, microvascular and metabolic) complications was ascertained by hospital discharge claims and estimated using Cox proportional hazard models.

Ascertainment bias in dementias: a secondary to tertiary centre analysis in Central Italy and conceptual review.

Background And Aims: Ascertainment bias (AB) indicates a bias of an evaluation centre in estimating the prevalence/incidence of a disease due to the specific expertise of the centre. The aim of our study was to evaluate classification of different types of dementia in new cases appearing in secondary and tertiary centres, in order to evidence possible occurrence of AB in the various (secondary to tertiary) dementia centres.

Methods: To assess the mechanism of AB, the rates of new cases of the different forms of dementia reported by different centres were compared.

Prospective phase II Study on 5-days azacitidine for treatment of symptomatic and/or erythropoietin unresponsive patients with low/INT-1-risk myelodysplastic syndromes.

Purpose: This phase II prospective study aimed to evaluate the efficacy and safety of 5-days azacytidine (5d-AZA) in patients with low-risk myelodysplastic syndromes (MDS). Second, single-nucleotide polymorphism (SNP) genetic profile and phosphoinositide-phospholipase C (PI-PLC) β1 levels were studied to evaluate possible biologic markers able to predict the hematologic response.

Experimental Design: The study tested a lower intensity schedule of azacytidine.

A 3-day randomized clinical trial to investigate the desensitizing properties of three dentifrices.

Background: The aim of the present study is to evaluate the relative abilities of three desensitizing dentifrices to provide rapid relief of dentin hypersensitivity (DH).

Methods: Using a double-mask, randomized design, three dentifrices: 1) containing 8% arginine and 1,450 ppm sodium monofluorophosphate; 2) containing 8% strontium acetate and 1,040 ppm sodium fluoride; and 3) containing 30% microaggregation of zinc-carbonate hydroxyapatite nanocrystals were compared after 3-day treatment. Participant's DH was evaluated at baseline and after 3 days using air-blast, tactile, cold water, and subjective tests.

[Analysis of differences among hygienic requirements of habitable garrets in Italian regions].

Recently the Italian Supreme Court has sentenced that garrets not suitable for common usage belong to the owners of the dwellings positioned below. These spaces may be transformed into living areas, which is particularly convenient in this moment of housing shortage. In this study the authors analyze the minimum hygienic requirements for transformed garrets established by each regional law, and underline the considerable differences authorized by the laws.

Prevalence of hyperandrogenic states in late adolescent and young women: epidemiological survey on italian high-school students.

Context: Most of the estimates of the prevalence of hyperandrogenic states refer to the general adult population.

Objective: The objective of the study was to estimate the prevalence of hyperandrogenic states in late adolescence and youth and to evaluate potential independent predictors.

Design: This was a cross-sectional study.

Migrant care workers as protective factor against caregiver burden: results from a longitudinal analysis of the EUROFAMCARE study in Italy.

Objective: The aim of the analysis is to assess the impact of privately employed migrant care workers (MCWs) on the burden of Italian family members who care for a disabled older person.

Methods: EUROFAMCARE is a one-year prospective survey carried out to provide evidence on the availability and use of support services by family carers of older people in Europe. In Italy, 990 family caregivers were enrolled and successful follow-ups were completed for 863 subjects.

Hepato-gastric and spleno-mesenteric arterial trunks: anatomical variation report and review of literature.

The celiac trunk is one of the main arteries arising from abdominal aorta and supplies blood to several abdominal organs. The typical branching in left gastric, splenic and common hepatic arteries undergoes relatively frequent variations. The authors report a rare variation of the celiac trunk in a Caucasian cadaver, with a hepato-gastric and a spleno-mesenteric arterial trunks which arise from the abdominal aorta in a routine dissection of a 98-year-old male cadaver.

Pathophysiological mechanisms linking depression and atherosclerosis: an overview.

It is well recognized that depression is independently associated with cardiovascular events. However, uncertainties remain on the pathophysiological pathways underlying the association between depression and coronary heart disease. In addition to the traditional cardiovascular risk factors, autonomic nervous system (ANS), low grade of inflammation, platelet and hypothalamic-pituitary-adrenal axis function and genetic factors may adversely impact the endothelium of the arterial wall.

Influenza vaccination recommended for all adults aged between 50 and 64 years: conceptual basis and methodological limitations.

In the first half of this year the experts of the Italian Society of Hygiene (SItI), along with those of other National Scientific Societies, agreed with the recommendations made by the USA CDC in 2009, and developed a proposal for a vaccination schedule (Vaccine Schedule for Life), in which influenza vaccination is recommended for all adults aged between 50 and 64 years. In the National Plan for Vaccinal Prevention 2012-2014, which was published just before the issue of the SItI Calendar but concluded earlier (end of 2011), influenza vaccination is recommended "only" for all persons > or = 65 years or included in one of the many at-risk categories. The issue is controversial and has generated considerable debate at national and international level.

Preliminary evaluation of the safety and efficacy of standard intravenous immunoglobulins in pregnant women with primary cytomegalovirus infection.

Hyperimmune globulins were reported to prevent and treat fetal cytomegalovirus (CMV) infection during pregnancy. Here, we report that infusions of standard human intravenous immunoglobulin significantly increase CMV IgG titers and avidity indexes in pregnant women, paving the way to their use for passive transfer of maternal CMV humoral immunity to fetuses. Preliminary data on perinatal outcomes of the first 67 newborns are encouraging.

Nuclear PI-PLC β1 and Myelodysplastic syndromes: from bench to clinics.

Myelodysplastic syndromes (MDS), clonal hematopoietic stem-cell disorders mainly affecting older adult patients, show ineffective hematopoiesis in one or more of the lineages of the bone marrow. A number of MDS progresses to acute myeloid leukemia (AML) with the involvement of genetic and epigenetic mechanisms affecting PI-PLC β1. The molecular mechanisms underlying the MDS evolution to AML are still unclear, even though it is now clear that the nuclear signaling elicited by PI-PLC β1, Cyclin D3, and Akt plays an important role in the control of the balance between cell cycle progression and apoptosis in both normal and pathologic conditions.

Amoxicillin and clavulanic acid vs ceftazidime in the surgical extraction of impacted third molar: a comparative study.

The objective of this work is to compare the effectiveness and the side effects of two different drugs, amoxicillin and clavulanic acid vs ceftazidime, used as antibiotic prophylaxis in the surgical extraction of third molars and to demonstrate that the use of second choice antibiotic has no significant advantages in comparison with a first choice antibiotic. One hundred and seven patients with impacted third molar were selected and divided into two groups: amoxicillin and clavulanic acid were administered to group 1 and ceftazidime to group 2 for five days after surgery and we observed the postoperative period. The statistical analysis showed no differences between the two groups which lead to the conclusion that there is no indication to routinely administrate intramuscular second-choice antibiotic prophylatic therapy (ceftazidime) in case of surgical extraction of the third molar.

(In)accuracy of blood pressure measurement in 14 Italian hospitals.

Objectives: The diagnosis and control of hypertension depend on accurate measurement of blood pressure (BP). The literature on the accuracy of BP recording by health professionals is, however, limited, and no study directly interviewed patients in the hospital setting. This multicenter cross-sectional study aimed at evaluating the compliance to current recommendations on BP measurement by health professionals directly from patients and to investigate potential predictors of higher quality in BP recording.

Effectiveness and harms of seasonal and pandemic influenza vaccines in children, adults and elderly: a critical review and re-analysis of 15 meta-analyses.

Fifteen meta-analyses have been published between 1995 and 2011 to evaluate the efficacy/effectiveness and harms of diverse influenza vaccines--seasonal, H5N1 and 2009 (H1N1)--in various age-classes (healthy children, adults or elderly). These meta-analyses have often adopted different analyses and study selection criteria. Because it is difficult to have a clear picture of vaccine benefits and harms examining single systematic reviews, we compiled the main findings and evaluated which could be the most reasonable explanations for some differences in findings (or their interpretation) across previously published meta-analyses.
